BIS-2-pyridyl glycol as a reagent for gravimetric determination of uranium,aluminium and beryllium

Bis-2-pyridyl glycol has been used for the gravimetric determination of uranium, aluminium and beryllium. The reagent quantitatively precipitates uranium from uranyl nitrate solution at pH 5.0–8.0, aluminium from potash alum solution at pH 5.2–8.5 and beryllium from beryllium sulphate solution at pH 7.5–9.5. The precipitate in each case is ignited to the corresponding oxide and weighed.
